Function of a Thermometer, Materials, and why they were chosen   ﻿ There are many ways a thermometer is used. It is used for measuring the temperature of a substance. This could be a solid, liquid, or gas. The thermometer could also be used for finding the boiling, melting, and freezing point of a substance. What would scientists do without thermometers? Many discoveries would not have been made if it wasn't for the invention of the thermometer. Another reason the thermometer was made was to measure the temperature of the human body. This is vital for a person's health. It is also used to find the temperature of the outdoors. This is helpful because people like to know how warm or cold it is outside.There aren't many materials in making a thermometer. There is glass, alcohol, and ink. The glass is used to hold in the alcohol. Scientists used glass because it is the least affected when introduced to different temperatures. Glass expands very little when it is put into a hot temperature. The alcohol was dyed because then the alcohol would be seen better. The ink is used to make the hash marks on the outside of the thermometer. This process is called calibration. There isn't much ink used because the hash marks are so little.
